One of these days is none of these days

One of these days is none of these days.

Prov. If you say you will do something "one of these days," you probably do not seriously intend to do it, and therefore it will not get done. Alan: When are you going to fix the garage door? Jane: One of these days. Alan: One of these days is none of these days. Jill: One of these days, I'll pay you the money I owe you. Jane: One of these days is none of these days.
